In the third Group C of 7 patients autogenous tooth bone graft (AutoBT) was used to fill the cavity. Patient’s third molar tooth is extracted and sent to tooth bank to get it grinded in granule form of 400- 800µm. Sterilization of the material is done. After enucleation and curettage this granular form AutoBT is filled in the cavity and then gingival flap is sutured back tightly.
Post operative care is taken by giving analgesic , NSAIDs and antibiotics is given for next 7 days for pain, swelling and to prohibit any infection.

To maintain the volume of alveolar ridge, strengthening the jaw bone and to give a good support to adjacent teeth, stable bone regeneration is required. There are various methods for the management of cystic cavity. Schulte described a method where collagen sponge soaked with antibiotics is placed in the cavity which stabilizes and controls the contraction of the blood clot. Later this method was modified by using centrifuged blood. The cavity can be filled with autogenous bone as graft material. But this will result in morbidity at the donor site. To overcome these problem surgeons came up with bone substitutes to stabilize the blood clot without the use of bone grafts. There are many types of bone substitutes based on their origin- autogenetic, allogenetic, alloplastic, xenogenetic. Mostly all bone substitutes are in granular form. Depending on the size, form and defect of the cavity these graft materials are used. In this study two materials are used for two different groups. Absorbable gelatine sponge is used in 51 patients and autogenous tooth bone graft (AutoBT) in 7 patients. Gelatine sponge- it is a sterile, absorbable, water-insoluble sponge which absorbs blood and provides area for clot formation. In this study gelatine sponge acts as obliteration of jaw cyst cavity .The gelatine sponge serves as a frame to support the granulation so that wound heals without any contamination and disruption of clots. The sponge itself is absorbed long before bone formation is complete, and the fibrous tissue which replaces it is invaded by blood vessels and eventually incorporated into bone Thus ossification of the bony defect takes place. The average reduction of the cavity size in this study showed about 26% during 3 months period with gelatine sponge filling. The gelatin sponges are getting modified by using poly-lactide-co-glycolide (PLGA
